The Woolsey Insulation Houston Guarantee
Every insulation job we complete in Houston carries a 365-Day Done Right Promise, and we put that promise in writing before the first bag of insulation comes off the truck. Here’s what that means for your home: if a repair or installation isn’t right within 365 days of the job, Woolsey Insulation Houston comes back and fixes it at no charge. You’ll get a written guarantee on every repair and installation, and if the work fails, the second visit is free. That’s the whole promise. No fine print, no prorated nonsense, no “call the manufacturer” runaround. Glenn Hartley, Owner, signs off on that commitment, and it’s been the backbone of how we operate since 2002. Whether we’re air-sealing an attic near Meyerland or installing spray foam in a Heights bungalow, the guarantee travels with the work.
What’s Covered
- Workmanship for 365 days. If an installation or repair isn’t done right within a full year, we return and make it right at no charge. The guarantee is written, not verbal.
- Materials handled correctly every time. We work with eight leading insulation brands including Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, and we install each one according to its specific requirements so the manufacturer’s material performance is never compromised by sloppy installation.
- Clean job site, every job. Part of the Kingswell Guarantee is leaving your home cleaner than we found it. That means no stray fiberglass in the hallway, no foam drips on the garage floor, no insulation dust tracked through the living room.
- On-time arrival with a committed window. When we schedule your insulation work, you get a committed arrival window in writing. We show up when we say we’ll show up, and if something changes, a real person calls you.
- Honest pricing before work begins. You receive a written price before any work starts, guaranteed, on every job, with no exceptions. The price on the paper is the price you pay. No door-step surprises, no sudden “discoveries” that double the quote.
How Much Does Insulation Work Cost in Houston?
Most attic insulation jobs in Houston run between $1,500 and $3,200 depending on square footage, existing insulation depth, and access. Spray foam insulation projects typically start around $3,000 and go up from there, because the material itself is more expensive and the installation is more involved. Before we start any work, you get the exact written number for your specific home. No ranges on a contract, no “we’ll see how it goes.” We measure, we assess, we write the price down, and that’s the number.
| Project Type | Typical Houston Range | What Affects Price |
|---|---|---|
| Attic insulation (blown-in fiberglass or cellulose) | $1,500 – $3,200 | Square footage, depth needed, access difficulty |
| Attic insulation (spray foam, open-cell) | $3,000 – $6,500 | Roof deck area, rafter depth, existing insulation removal |
| Attic insulation (spray foam, closed-cell) | $5,000 – $10,000+ | Higher material cost, superior R-value per inch, moisture barrier properties |
| Air sealing + insulation combo | $2,200 – $5,000 | Number of penetrations, attic accessibility, existing insulation condition |
Houston’s climate shapes these numbers in ways homeowners don’t always expect. A home in Kingwood that fights East Texas humidity all summer benefits from closed-cell foam’s moisture resistance, while a mid-century ranch in Sharpstown might need nothing more than a blown-in fiberglass top-up. We give you the written price for your home, not a generic Houston average. Call (903) 447-8369 for a free estimate and you’ll see exactly what we mean.
Our Satisfaction Promise
If you’re not satisfied with the insulation work we’ve done in your Houston home, we want to hear about it. Not next month, not after you’ve stewed on it for a season. Call the office. A live person answers, 24 hours a day, 7 days a week. There’s no voicemail maze, no automated system, no call-back window that leaves you waiting. Tell us what’s wrong, and we schedule a return visit to make it right. If the work fails within the guarantee period, that second visit is free. The Kingswell Guarantee covers it: a clean job site, a written guarantee on the work, and a free return visit if any repair fails. We’ve operated this way since 2002 as part of the Kingswell family of independently owned and operated insulation companies, and the promise has never changed. Glenn Hartley owns this location and answers for the work personally. If something isn’t done right, he wants to know about it before it becomes a bigger problem in your attic.
Licensed & Insured Backing
Paperwork matters, but only if there’s something real behind it. Woolsey Insulation Houston is licensed and insured, and every technician who walks through your door is background-checked and uniformed so you know exactly who is in your home. Insurance protects your property if something goes wrong. Licensing means we’re accountable to the state of Texas for the work we do. Combined with the 365-Day Done Right Promise, that’s the real guarantee: a company with legal accountability, financial protection for your home, and a written commitment to fix our mistakes. Not every insulation contractor in Houston operates that way. We do, and it’s been that way since day one.
What Does the 365-Day Done Right Promise Actually Cover?
The 365-Day Done Right Promise covers our workmanship on every insulation installation and repair we complete in Houston. If the insulation settles, shifts, or fails within 365 days of installation, we come back and correct it at no charge. If a spray foam application didn’t cure properly or left gaps, we fix it. If the blown-in insulation wasn’t installed evenly to the depth we specified, we make it right. The promise is included on every job, in writing, from the smallest attic top-up to a full spray foam conversion in a Memorial-area home. What it doesn’t cover is damage from third parties, structural changes to the home, or issues caused by roof leaks or pest intrusion after installation. We’re straightforward about that because a guarantee only means something if both sides understand it.
Why We Put the Price in Writing Before Work Begins
Because a handshake doesn’t hold up when the temperature in a Houston attic hits 130 degrees and a contractor decides the job is suddenly “more complicated.” The written price is part of the Kingswell Guarantee: say the price, show up in the window, leave it cleaner than you found it, put the guarantee in writing, come back if it fails. We deliver that written price before any work begins, every job, no exceptions. It includes materials, labor, and cleanup. If something changes during the job, we stop and talk to you before proceeding. No surprise line items, no “change orders” that appear after the work is done. Glenn Hartley built this Houston location on that principle, and it’s the reason homeowners from Clear Lake to Cypress call us back for their next insulation project.
How Does a Guarantee Claim Work in Houston?
If you believe your insulation work isn’t holding up, call (903) 447-8369. A live person answers, day or night. Describe the problem. We review your job file, which includes the written guarantee from installation day. If the issue falls within the 365-day window and relates to our workmanship, we schedule a return visit at no charge. The technician who arrives will be background-checked and uniformed, just like the first visit. We’ll assess the problem, explain what we’re seeing in plain language, and fix it. Most guarantee claims in Houston involve minor adjustments: a section of blown-in insulation that settled after heavy humidity, a small area of spray foam that didn’t fill a gap completely. Those are quick fixes, and we handle them without making you jump through hoops.
Common Questions About Our Insulation Warranty
Is the guarantee really free?
Yes. If the work fails within 365 days due to our workmanship, the return visit and the fix are free. That’s the Done Right Promise, and it’s in writing on every job.
What if I’m not sure the work was done right?
Call us. We’d rather inspect the job and find nothing wrong than have you worry about your attic insulation through a Houston summer. The inspection is part of standing behind our work.
Does the guarantee cover the insulation materials themselves?
Manufacturer warranties on materials like Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber products are separate from our workmanship guarantee. We can help you understand what your material warranty covers, but our 365-Day Promise is specifically about the quality of our installation.
Who owns the guarantee if the company changes?
Woolsey Insulation Houston is independently owned and operated under the Kingswell banner. Glenn Hartley owns this location. The guarantee stays with the location, not with a corporate entity in another state.
